SKNodes를 하나씩 실행하지 않고 차례로 실행합니다.

Question

화면 중간에서부터 화면 가장자리까지 작은 별을 발사하고 싶습니다. 사실 이것이 완벽하게 작동하지 않는다는 사실을 감안할 때 다른 문제가 있습니다. 여러 개의 SKNode (별)를 차례로 발사하려고합니다. 그러나 별이 떨어지는 이상한 이유로 새 별이 실행 중일 때 이전 별이 제거됩니다. 이것은 항상 다른 Scene을 추가하기 때문에 가능하지만, 이미 viewDidLoad에이를 성공적으로 추가하려고 시도했습니다. 그리고 o, VM을 사용하고 있기 때문에 xCode가 충돌하기 때문에 .sks 파일에 액세스하거나 볼 수 없기 때문에 모든 코딩을 ViewController에서 수행해야합니다. 고맙습니다!

이궁을! viewController에서 해당 코드를 실행하면 안됩니다. 씬을로드 한 다음 SKScene 내부에서 스타 생성을 수행해야합니다.
